Ecotoxicological Risk Assessment for Roundup ® Herbicide
Glyphosate-based weed control products are among the most widely used broad-spectrum herbicides in the world. The herbicidal properties of glyphosate were discovered in 1970, and commercialExpand
Ecological risk assessment of atrazine in North American surface waters.
The triazine herbicide atrazine (2-chloro-4-ethylamino-6-isopropyl-amino-s-triazine) is one of the most used pesticides in North America. Atrazine is principally used for control of certain annualExpand
Bioconcentration and tissue distribution of perfluorinated acids in rainbow trout (Oncorhynchus mykiss).
TLDR
Sulfonates had greater BCFs, half-lives, and rates of uptake than the corresponding carboxylate of equal perfluoroalkyl chain length, indicating that hydrophobicity, as predicted by the critical micelle concentration, is not the only determinant of PFA bioaccumulation potential and that the acid function must be considered. Expand
Biological monitoring of polyfluoroalkyl substances: A review.
TLDR
The pattern of contamination in wildlife varied among species and locations suggesting multiple emission sources and knowledge gaps with respect to the transport, accumulation, biodegradation, temporal/spatial trends and PFS precursors have been identified. Expand
Aquatic ecotoxicology of fluoxetine.
TLDR
The findings indicate that the magnitude, duration and frequency of fluoxetine exposure in aquatic systems requires further investigation and mechanistic toxicity of fluxetine in non-target biota, including behavioral responses, are clearly not understood. Expand
Dietary accumulation of perfluorinated acids in juvenile rainbow trout (Oncorhynchus mykiss).
TLDR
Sulfonates bioaccumulated to a greater extent than carboxylates of equivalent perfluoroalkyl chain length, indicating that hydrophobicity is not the sole determinant of PFA accumulation potential and that the acid function must be considered. Expand
Endosulfan, a global pesticide: a review of its fate in the environment and occurrence in the Arctic.
TLDR
Endosulfan does fulfil several of the criteria under the UNEP Stockholm Convention for designation as a persistent organic pollutant and is present in marine mammals, although there is uncertainty in the various Arctic biota datasets due to differences in analytical techniques. Expand
Probabilistic hazard assessment of environmentally occurring pharmaceuticals toxicity to fish, daphnids and algae by ECOSAR screening.
TLDR
(Q)SAR's can be important prioritization tools for subsequent experimental risk assessment of pharmaceuticals in surface waters, due to the prevalent lack of ecotoxicological data. Expand
Response of larval Xenopus laevis to atrazine: assessment of growth, metamorphosis, and gonadal and laryngeal morphology.
TLDR
It is concluded that environmentally relevant concentrations of atrazine do not influence metamorphosis or sex ratios and do not inhibit sexually dimorphic larynx growth in X. laevis. Expand
Effects of 25 pharmaceutical compounds to Lemna gibba using a seven-day static-renewal test.
TLDR
Injury symptoms were comparatively uniform and consistent among chemical classes while degree of phytotoxicity varied considerably; both of these criteria varied markedly between classes. Expand
